CHECK-ROWER.

I SPECIFICATION forming part of Letters Patent No. 308,834, dated December 2, 1884.

Application filed May 16, 1884. (No model.)

(given to the button-fork by the wire) to the slide-bar of the planter, the object being to simplify these devices, and also to dispense with the cumbrous frame and its attachments ordinarily used in the construction of checka is held by a pin, on the end of a.

rowers.

Two sheets of drawings illustrate thisinvention, Sheet 1, with Figure 1, and Sheet 2 with Figs. 2, 3, and 4:.

Fig. lis an isometric View of one-half of the front section of a two-horse corn-planter. Fig. 2 is an end elevation of the main cross-bar of the same with my improved check-rower attached thereto. Fig. 3 is a top view of the same with a section through line a: broken away to exhibit the devices for operating the slide-bar of the planter under the right arm of the bracket. Fig. 4 is a front view of the T- shaped lever which transmits the movement of the button-fork to the slide-bar of the planter.

A is the front or runner section of a cornplanter. B is the check-rower attachment, which is attached to an elevated bracket, 0, having its lower end turned at about a rightangle to the stem, and is fastened to the end of the main cross-bar F, on either side of the planter-section A, by a single bolt, 6. The brackets are not connected with each other except by the planter-frame itself, but each bracket and the check-row devices attached thereto is separate and distinct from the other.

As the check-rower attachment is the same upon both sides of theplanter, duplicate drawings of the device are considered-unnecessary. The bracket 0 has its head end, which islong and narrow, extended toward the front and rear, and has a wooden bar, on the top, upon either end of which are attached the usual guide-pulleys,p, p, and 1)", respectively;

At the center of the bracket and bar I) is the button-fork a,which extends down through a long slot, b, in the middle of the bar and bracket, and is pivoted to the latter below its head, in the middlevertical line of its stem, over the end of the main crossbar, by a horizontal bolt, a.

As may be seen in Fig. 2, the fork-lever or button-fork (4 extends below the head, is bent at an angle rearward from its pivot, and has its lower end out down to form an angle, if, on either side, in the middle line of the same, (outside and on the inner side of its stem.) Below the shoulder formed by this downwardly-projecting angle, and directly opposite thereto in near approximation, is seen the angle a of a loose collar, a, which latter Between the two angles et -a is pivoted the rear end of the long flat horizontal bar I), which transmits motion from the fork a to an oscillating T- shaped lever 11'. To form bearing-points for the journals of lever b, the

front end of the head h of the bracket 0 depends downward, backward, and upward, forming a hanger, c, with a vertical bearing or box, If, at its terminal or inner end, opposite to which, on the under side of the head, is another bearing, h, in which bearings are pivoted the head end of lever 12, upon its two opposite vertical journals, d and d seen projecting from the axial line of the head d, on the upper and lower side of the same, in Fig. 4, which shows a front view of the head. The head at lies in a plane above the stem of lever 12 as will be noticed by reference to Fig. 2, and has a long horizontal slot, (2, therein extending from one side to the other, and

through this slot extends the front end of lever b, which latter has a pin, 0 and a, vertically through it on the rear and front sides of the head at, respectively. The pin 0 is formed with an angle on its front side, and engages with a notch, c", seen in the head, on the rear side, in Fig. 3, near each end of the same. To guide the pin 0 into this notch there is an angular projection, (1, extending rearward on the outside of each of the notches 0. These projections prevent the pin from being freed from the line of its engagement, as the pin a i cannot be drawn backward (from the rebound of lever a) beyond the projection d, but lies with its angle inside and forward of the latter before engaging the notch c to push that end of the head forward 011 which it lies. The rear end of the stem of lever b is connected with the slide'bar D of the planter by rod 1", each end of which is turned up at right angles, and is pivoted in the stem of lever b, and in a lug, f, of a clamp-plate or clip, E, adjustably attached to the slide-bar, respectively.

The operation of the check-rower can be understood by reference to the figures, and to Fig. 3, particularly, which shows in dotted lines the movements of levers b and b. WVhen the button-fork lever a is engaged by a button of a check-row wire and thrown backward, lever bis thrust forward, its rear pin, 0, engaging notch c, and throwing the outside end of the head (1 of lever 1) forward to the position seen in the dotted lines. Lever a now being released from the button, its lower end is thrown backward by the reaction of spring 8 attached to the fork, (in the usual manner,) and lever Z) is pulled backward, its front pin, 0, comes in contact with the front of the head (1, and this (front) end of the lever b is drawn to the opposite end of the head (I, (in the slot d,) which latter, being thrown back, mak es this the shortest route for said lever b when drawn backward. It is now in the position seen in the dotted lines before referred to, and when the next button of the wire engages fork a the pin 0 of lever b engages the notch c on that side of the head in which it lies, and it is again thrust forward and the movement repeated as before,

the slide-bar D of the planter being thrown in' the opposite direction. The stem of lever Z) is provided with a series of holes, a n, to ad just the throw, and the clamp-plate E can also be adjusted by bolts f, which secure its upper and lower sections together over the slide-bar. The horizontal slot d in the head of lever b has an angle, 6*, at the middle of its lower side elevated above the plane of that side of the slot, for the purpose of preventing the end of lever b from dropping toward the lower end of the slot when operating the planter on a side-hill,' and to retain it at either end of the slot preparatory to its movement from one end of the latter to the other.

By reference to Figs. 2 and 3 it will be seen that the front end of thethrust-lever b has a central point or angle, 0, with inclined sides. The hanger-bar c has also a similar angle, 0 on the rear side, so that whenlever b is thrust forward its end must invariably pass on one side of the angle 0 of the hanger, thus preventing any danger of a lock or dead point in its throw.

In order to adjust the check-rower forward or backward to time its movement the top of bracket 0 is made in two parts, h and h it being divided horizontally and longitudinally,

as seen in Figs. 1 and 2, and in the details D of the latter figure. The entire top plate, h, with bar If and the check-rower movement attached thereto slides endwise on the lower plate, which is attached to and is a part of the bracket itself. A longitudinal slot, 6", in the plate h", through which the vertical bolt 0 extends, allows of this adjustment. As the hanger-plate h with all of the operative de vices of the check-rower is moved in making the adjustment in either direction their relation to each other remains unchanged.

The detail figure D shows a side and top view of the parts at the point of their adj ustment.

I claim as my inventi0n- 1. In a check-rower movement, the con1bination of the pivoted button-fork lever, the thrust-lever connected directly with said button-fork lever, and the T-shaped oscillating lever having a horizontal slot in the head of the same, as set forth.
